Vivitek Qumi Pocket Projector

It's amusing to think that just a few years ago, a projector like this would have been 10x the size and 20x the price.

Actually, a projector like this couldn't have existed a few years ago, as it's got LEDs, which only recently have been bright enough for projector use.

The Qumi is a roughly the size of a small paperback book. Inside, in addition to the LEDs, is a 1280x800 DLP chip. There's no zoom, and the lens is focused manually.

Though called a "pocket projector," briefcase projector would be more like it. It's not battery powered, requiring A/C and a small external power brick. It's certainly more portable than a regular projector, but it's not one of the tiny pico projectors that can truly fit in your pocket.

Setup

The back panel is a little weird, with micro SD and mini HDMI. There's plenty of space, seemingly, for full sized versions of either. So you'll need to invest a few dollars in a mini HDMI cable. One is included, but it's only a few inches long.

There's a USB connection to play back music, movies, and images from a flash drive. A/V in and out and a "Universal I/O" (for an included RBG PC breakout cable) round out the connections. The tiny built-in speaker is audible, barely.
